"12 designates clodownward pressure ofthehands'ot the. atsure caps: having a detachable threaded `enf each ofsaid levers being' pivoted intermediate its ends to one of the side bars2 of the su ortincr frame to swing horizontall to C d carry itswheelengaging portion into and out oit engagement with the tire of oneof the wheels 4, 5. The pairs of levels 13, 14, are connected at theirinner end portions to a longitudinally extending rod 15 to operate inunison, said rod having studs 16, 17, engaging slots 18, 19, in theinner end portions of said levers. The rod 15 at its rear end ispivotally connected with an arm 20 of an angle lever, which is mountedfor vertical oscillation upon a transverse shaft or bar 21 located atthe rear of the side bars 2, said shaft or bar being shown secured tothe lower push bar sections 6. To the other arm 22 oit' the angle leveris pivotally connected one end of a rod 23. This rod 23 at its other endhas branches 233L which are pivotally connected to the upper slidablepush bar sections 7, the connection between the pairs of levers 13, 14,and the upper slidable push bar sections 7 being such that when thehandle bar 8 and upper push bar sections 7 are moved upwardly to theposition illustrated in Figures 1, 2 and 4 of the drawings, the pairs oilevers 13, 14 will be moved simultaneously to carry their wheel engagingportions 13, 14u into engagement with the wheels 4 and 5, as shown inFigure 3, and upon downward pressure of the handle bar 8 said pairs oflevers 13, 14 will be swung to move their wheel engaging portions 13,14a out of engagement with the wheels 4 and 5.

The coiled expansion springs 11 act to normally maintain the upperslidable push bar sections and the handle bar 8 forced upwardly inelevated position, the brake mechanism being normally set to hold thecarriage against movement. As will be understood by a relatively slightdownward pressure upon the handle bar 8, thefbrake mechanism is releasedand held in operative position.

Tension springs 24-24, may also be employed, if desired, to assist thecoiled springs 11-11, in maintaining the upper push bar v sections 7 andhandle 8 in elevated position, said springs being arranged as shown withthe opposite ends thereof connected rrespectively with the longitudinalrod 15 and the side bars 2 of the supporting frame.

Means is provided for locking the upper push bar sections 7 in lowerposition to the lower push bar sections G, as illustrated in Figure 5 ofthe drawings, and locking the brake mechanism in inoperative position.

Any vsuitable means may be employed for this purpose, that shown in thepresent instance comprising chain sections 25 secured to the lower pushbar sections 6, and snap hooks 26 on the upper push bar sections 7, thelinks of said chain sections 25 being adapted to be engaged with thesnap hooks 26, as shown in Figure 5, when the upper push bar sections 7are moved to lower position.

27 designates a. fender mounted on the forward ends of the side bars 2of the supporting frame,

It will'be noted that the special construction yand arrangement of partshereinbefore set forth, provides brake mechanism of a simple, efficientnature, adapted to be easily controlled through the handle bar forpropelling the carriage, the brake mechanism acting automatically tohold the' carriage against movement when the hands of the attendant areremoved from the handle bar, and being easily released and held ininoperative position solely by downward pressure upon the handle bar inpropelling the carriage, the handle bar being entirely free orunobstructed by other parts.
